Bearing;- openings 10 and 11 are p'lew'fdetl ih the "end plate 3 and 41 r' s' 'ee 't'ivel to receive bearing ftj'r fa cylindtichl platen 1.2. The lis'htil. paper deflector '01" comh'ined pap'er apron and table 13 6f Slightly flexible sheet metal ezitends sitibetantiallj th i'ohghbut the Iehgth of the carriage heneath the platen. terminating at its "u'pp ei' teat ed'tp let in the rear bf the plateh and at its" fi'd'nt iedfie beneath the firintinfi line at the f om of the platen. The usflal com payativdy heavy sheet i'hetal suemrting tiip 15 is riveted to theho ttd l'n (if the defle'ctm efitend through ut the length theireof. Each "end' (it the strip 15 has an uptqrn'ed bar 16 st'o'ttd vertiallv with the upper end of the lot elesed and its l wer end open. These slatted ears, censtitqte bea ings by which the aper dfleCtOli detachably supported On joih 17 that meme inwardly ftdnj supporting zirnigtlS. These arms are fixed to a rock shaft 19 jhurhald at their ends iii bearing iii the end plate 3 and 1; Each arm 18 1m an iflwardly e5;- tending pfojeeti'on 20 mpped to retake an adjusting Scre\'\ 21 with a hole theiethreflg' h to receive on end of contractile 5 m which has its opposite "ehcl cemented to a pin 23 that attends inwamly tretti the assh'ciatefl enctplatesfi or t of the ca riage. The power rat thee sip-rings; is exerted in move the M1119 in dotted lines in Fig. 1, to form hook-like bearing members for the shafts or spindles 26 and 27 respectively. Each of these shafts is slightly flexible and extends substantially throughout the length of the platen and is loosely seated in its bearings in the associate supporting strips 24: or 25. A set of coaxially arranged main feed rollers 28 (three in number in the present instance) is loosely mounted on the shaft 26 and extends substantially throughout the length of the platen. A second set of co-axially arranged forward main feed rollers 29 (three in num ber in the present instance) is loosely mounted on the shaft 27 and extends substantially throughout the length of the platen. The present construction embodies a special arrangement of the feed rollers 28 and 29. Thus it will be seen that the left-hand termi nal feed roller 28 is comparatively short, whereas the two remaining feed rollers of the set are comparatively long. On the other hand, the right-hand feed roller 29 is comparatively short, whereas, the other two rollers 29 are comparatively long. By this staggered arrangement of the feed rollers there is a fore-and-aft break-joint effected between the rollers of the two sets, and there is no space between the rollers of one set that is not crossed by a roller of the other set. Therefore there is no point in the length of the two sets of rollers where a roller of either one set or the other does not co-act with the paper to effectively feed it. Moreover, there is no vertical line or field throughout the width of the paper 'where one or another feed roller 28 or 29 does not bear with a substantially uniform pressure. Therefore in the production of carbon copies there is no observable tracking from the carbon sheets on the carbon copies, as sometimes occurs when the front and back feed rollers are mounted in tandem arrangement or foreand-aft alignment with spaces between them where the feed rollers of neither set coact with the paper. In the present construction the two relatively short terminal rollers are of the same length and the four relatively long rollers are of the same length.

The strip or member near the ends thereof is provided with two forwardly projecting bendable fingers 30 and two rearwardly extending bendable fingers 31. The fingers 30, when in effective position, cross the axis of the shaft 27 to limit the endwise displacement of said shaft and aid in assembling the parts. The fingers 31 in a like manner are adapted to coact with the shaft 26.

Openings are provided in the deflector 13 through which the feed rollers 28 and 29 may extend to bear against the platen under the pressure of the springs 22. A light spring 32 is connected at one end to an ear 33 on the strip 15 and is connected at its other end to a pin 23. There are two of these springs 32, one at each end of the deflector 13 to prevent it from dropping freely away from the platen at its forward edge when feed rollers are released, as shown in Fig. 3, although the slight force exerted by these springs is just about suflicient for this purpose.

I employ the usual release mechanism in order to move the paper deflector and feed rollers 28 and 29 to releasing position, shown in Fig. 3. This mechanism includes a pin 34 that projects outwardly from the left-hand supporting arm 18 and forms a pivot for a link 35. This link forms one member of a toggle, the other member of which is formed by a release lever 36 pivoted on a headed screw pivot 37 received at its threaded end in a tapped opening in the end plate 3. The short arm 38 of this lever is pivoted at 39 to its companion toggle member 35, whereas the long arm of the lever 36 terminates in a finger piece 4.0 by which the parts may be controlled. When said finger piece is shifted from the Fig. 1 to the Fig. 3 position, where it is arrested by a rock shaft 41, the toggle will be shifted to the substantially straight line position, represented in Fig. 3, where it and the parts cont-rolledthereby, are held against return movement by the dead centering of the toggle. This movement of the toggle resulted in forcing the left-hand supporting arm 18 from the Fig. 1 to the Fig. 3 position against the power of the left-hand springs 22 and 32, and also in rocking the shaft 19. The rocking of this shaft causes the supporting arm 18 at the other end of the carriage to partake of the movement of the left-hand arm 18 and to release the pressure of both sets of the springs 32 and 22 on the paper deflector and feed rollers 28 and 29.

In accordance with my present invention I provide paper fingers and marginal paper feed rollers mounted on a support above and in the rear of the platen and which are adjustable longitudinally of the platen. I also have provided means whereby a movement of the finger piece 40 to releasing position is additionally effective to release the paper fingers and margin feed rollers, and whereby said paper fingers and margin roll-- ers may be independently shifted to releasing position or may be moved beyond said position to and maintained in an inoperative lation of the work sheets in the machine or with their introduction'therein. This materially facilitates making corrections or erasures on work sheets in the machine, where ordinarily the fingers, if not mounted so that they may be moved to such thrownofi position, might interfere with this .work

and might require a separate displacement I section a and b is carried up and extends substantially in a horizontal position where the associated spring 57 will coact therewith and bear against the center of the shaftto hold the parts in the shifted position indefinitely, or until the paper fingers are swung down into effective position by the operator.

In order to automatically release the paper fingers when the feed rollers 28 and 29 are released, I provide the toggle link 35 with an extension or arm 59 carrying an inwardly extending pin or contact 60 at the free end thereof. This pin underlies and coacts with a downwardly and forwardly extending crank arm 61 secured to the shaft sec-v tion a near its outer end. In the present instance this arm 61 is formed from sheet metal, and as part of a yoke-like supporting socket 62 shaped to conform to and engaging the shaft section on three sides, as shown in Fig. 3. A headed screw 63 is re ceived at its threaded end in a tapped opening in the shaft section a after having passed through a hole supporting socket and thus firmly connects the crank arm 61 to said shaft section.

When the finger piece 40 is moved from the Fig. 1 to the Fig. 3 position to release the feed rollers, the straightening of the toggle causes the pin 60 to coact with and lift the arm 61. This results in turning the two-part rock shaft 41 and in automatically moving the paper fingers to releasing position shown in Fig. 3, holding them in such position until the parts are returned to effective position by moving the finger piece forward to the Fig. 1 position.

It will be observed that while there is an operative connection between the feed roller releasing means and the paper fingers, nevertheless this connection is such that it does not interfere with the separate and independent movement of the paper fingers to releasing position shown in Fig. 3, or to the further thrown-off position hereinbefore described.

It will be seen that by my present invention I have provided simple and highly efiicient paper feed mechanism for accomplishing the results pointed out, and that such means may be readily incorporated in the Remington-noiseless No. 6 or the noiseless No. 4 or No. 5 machines without material modification of the features of construction existin in such machines.

While I have described the present construction with considerable detail it should be understood that various changes may be made, and parts thereof may be employed without others, without departing from my invention as it is defined in the accompanying claims.
